The Role of Non-Adaptive Design Doctrine in Evolutionary Thought

Abstract

Charles Darwin’s theory of evolution was, to a certain extent, influenced and shaped by external factors, including the milieu of ideas in the early-nineteenth century, regarding how the natural world should be understood. Therefore, these ideas and their influences have received considerable attention. The role of non-adaptive design ideas, however, has not been fully explored. In particular, Darwin’s requirement and rejection of the religious doctrines of adaptive and non-adaptive design, respectively, are important and often unappreciated. Here, I analyze these ideas and how they influenced Darwin’s theory of evolution. I find they played an important role in both his theory development and justification, revealing a core theological belief in Darwin’s theory; namely, that the creator would not create non-adaptive designs. This paper explores this belief and its context.
